Mounted on the unthreaded portion of the tube 9 is a collar 2! having a disk flange 22 formed on one end thereof, and the flange 22 is provided with lugs 23 which are mounted in the grooves 20. The free end of the extension I is convexed as best shown in Figure 3 and disposed between the convexed free end and the disk flange 22 is a split washer 24, the latter having a concaved face to fit the free end and a fiat outer face for re ceiving the disk flange, and the Washer is formed from flexible material so as to readily expand or contract for securing and releasing the mouth piece with respect to the stem. Disposed between the disk fiange 22 and the collared portion I3 is a coil spring 25 which is forced against the flange 22 upon rearward movement of the travelling member for expanding the washer in binding engagement with the wall of the chamber.

From the above description and disclosure of the drawing, it will be obvious that upon rotation of the mouth piece in one direction it will cause the member l4'to travel forwardly on the tube 9, thereby removing obstructions from the passage 5, and upon rotation of the mouth piece in an opposite direction the member 44 will travel inwardly on the tube and against the coil spring 25 which moves the flange 22 against the washer 25, thereby causing the washer to expand into binding engagement with the chamber for fixedly associating the mouth piece with respect to the stem as will be apparent.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is:

1. A tobacco pipe comprising a bowl, a stem for the bowl having a passage communicating with the bore thereof, a mouth piece received in the stem, movable means on the mouth piece, means carried by the movable means and movable through the passage to remove obstructions therefrom upon rotation of the mouth piece in one direction, expansible and contractable means on the mouth piece andacted upon by the movable means to be expanded in binding engagement with the stem upon rotation of the mouth piece in an opposite direction for securing the latter to the stem.

2. A tobacco pipe comprising a bowl, a stem for the bowl and having a passage communicating with the bore thereof, a mouth piece frictionally mounted in the stem, a tube extending from the mouth piece and received in the stem, a travelling member threaded to the tube for movement longitudinally thereon, means to prevent rotation of the travelling member, and means extending from the travelling member for movement through the passage to remove obstructions therefrom upon rotation of the mouth piece.

3. A tobacco pipe comprising a bowl, a stem for the bowl and having a passage communicating with the bore thereof, a mouth piece received in the stem, 2. tube extending from the mouth piece, a hollow travelling member including a collar threaded on the tube for movement longitudinally thereof, means to prevent rotation of the travelling member, a pin extending from the outer end of the travelling member and received in the passage to remove obstructions therefrom upon rotation of the mouth piece in one direction, expansible and contractable means on the tube, and means engageable therewith for expanding the same in binding engagement with the stem and acted upon by the travelling member, upon rotation of the mouth piece in an op posite direction.

4. A tobacco pipe comprising a bowl, a chambered stem for the bowl and having a passage communicating with the bore thereof, a mouth piece including an extension frictionally mounted in the stem, a tube secured to the mouth piece and projecting through and beyond the extension, a travelling member threaded on the tube for movement in the chamber of the stem, a pin secured to the travelling member and movable through the passage to remove obstructions therefrom upon rotation of the mouth piece in one direction, expansible and contractable means on the tube, collared means engageable with the expansible and contractable means, and a coil spring movable against the collared means by the travelling member for movingthe expansible and contractable means against the extension for expanding the same into binding engagement with the stem upon rotation of the mouth piece in an opposite direction for securing the latter to the stem.
